    CEans,

    Those who are looking for a mini-project in electronics - can try to build a proximity sensor.

    Wikipedia says: -

    A proximity sensor is a <a href="https://en.wikipedia.org/wiki/Sensor" target="_blank" rel="noopener noreferrer">Sensor - Wikipedia</a> able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an <a href="https://en.wikipedia.org/wiki/Electromagnetic" target="_blank" rel="noopener noreferrer">Electromagnetic</a> or <a href="https://en.wikipedia.org/wiki/Electrostatic" target="_blank" rel="noopener noreferrer">Electrostatic</a> field, or a beam of <a href="https://en.wikipedia.org/wiki/Electromagnetic_radiation" target="_blank" rel="noopener noreferrer">Electromagnetic Radiation</a> (<a href="https://en.wikipedia.org/wiki/Infrared" target="_blank" rel="noopener noreferrer">Infrared</a>, for instance), and looks for changes in the <a href="https://en.wikipedia.org/wiki/Electric_field" target="_blank" rel="noopener noreferrer">Electric Field</a> or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a <a href="https://en.wikipedia.org/wiki/Capacitive" target="_blank" rel="noopener noreferrer">Capacitive</a> or <a href="https://en.wikipedia.org/wiki/Photoelectric" target="_blank" rel="noopener noreferrer">Photoelectric</a> sensor might be suitable for a plastic target; an <a href="https://en.wikipedia.org/wiki/Inductance" target="_blank" rel="noopener noreferrer">Inductance</a> proximity sensor requires a metal target.


    How's the idea? Easy? Give it a try and share your learnings with all of us here! :smile:
